The first title in the series, Prince & Knight, is a new take on traditional fairy tales, which tells the story of a prince searching for a princess to marry who teams up with a knight to save his kingdom from a dragon. "Together they defeat the dragon, and find love in the process," reads the synopsis.

School Library Journal called the book, written by Daniel Haack and illustrated by Stevie Lewis, "an illuminating fairy tale for young readers to be able to see that not every prince would like to marry a princess." It's available now in bookstores and online.

The second book in the series, titled Jack (Not Jackie), will tell the story of a girl named Susan coming to accept her younger sibling, who identifies as "Jack" instead of "Jackie." It was written by Erica Silverman and illustrated by Holly Hatam, and will be available in October. GLAAD and Bonnier reportedly intend to publish four titles per year, in various genres, for toddlers up to 14-year-olds.

"GLAAD is committed to advancing positive representation of LGBTQ lives, experiences and stories at every stage of our lives, and books are a natural progression to encourage awareness, kindness, and acceptance at an early age," GLAAD President and CEO Sarah Kate Ellis said in a statement.

Shimul Tolia, CEO of Bonnier Publishing USA, added, "We're proud to be partnering with GLAAD … and do our part to make classrooms, bookstores, and even the playground a more inclusive environment."
